Technical insights and discoveries from my development journey

Flutter Camera Package Limitation

Flutter • Camera

Published: 02.02.2026

The popular camera package doesn't provide a way to manually select camera resolution. Instead, it uses an internal fallback mechanism that automatically selects the "most compatible" resolution, which can be significantly lower than what your device actually supports. This can result in lower quality photos than expected.

iOS iBeacon: Wake Your App from Termination

iOS • iBeacon • BLE

Published: 02.02.2026

iBeacon uses Bluetooth Low Energy (BLE) to create tiny transmitters that can wake your iOS app from the background or even from a completely terminated state. When a user walks near a beacon, iOS automatically wakes your app and gives you ~10 seconds to perform tasks. However, you can only monitor up to 20 beacon regions simultaneously, and iOS only wakes your app for region enter/exit events, NOT for distance measurement. For continuous BLE connections, you must declare bluetooth-central background mode in Info.plist.

Apple Docs

App Store "What's New" Text Rejection

iOS • App Store

Published: 02.02.2026

Apple rejects app updates if your "What's New" text mentions competitor platforms, especially the word Android. Even innocent release notes like "Fixed push notifications on iOS and Android" will trigger a rejection. Cross-platform developers often write unified release notes and forget to customize them, causing delays. Always maintain separate, platform-specific release notes that focus on the iOS experience only.
